WINDOW.

To all whom 'it may concern:

Be it known that I, OvILA BAIGN, a subject of the King of Great Britain,and resident of 19 St. George street, in the city and district ofMontreal, in the Province of Quebec, in the Dominion of Canada, haveinvented certain new and useful Improvements in IVindows; and I dohereby declare that the following is a full, clear, and exactdescription of the same.

The invention relates to improvements in windows, as described in thepresent specification and illustrated in the accompanying drawings thatform part of the same.

The invention consists essentially in the novel construction andarrangement of parts whereby the sashes which are hinged to suitabledrop pieces or slides, contained within the vertical grooves in theframe, are made to fold up in their closed position against juttingvertical and horizontal pieces in the window frame and to open and closewith the sliding of said drop or slide pieces and balanced by thecounter-weights as customary in window construction.

The objects of the invention are to devise a window in which the sashesmay be drawn inwardly for the purpose of cleaning the outer surface ofthe glass, without danger to the person cleaning the window, to providein such windows a perfectly tight construction so that t-he ingress ofcold, when the window is in its closed position, may be absolutelybarred, and generally to increase the eiiiciency of this particular typeof window, without increasing the cost of production.

In the drawings, Figure 1 is a perspective view of the invention showingthe sashes half way drawn down from their vertical position. Fig. 2 is across sectional view on the line A-B in Fig. 1. Fig. 3 is a perspectivedetail partially in section to disclose a spring for returning thewindow to its vertical position. Fig. 4 is a perspective detail of aportion of the frame showing a weather strip applied to the juttingportion.

Lilie numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is a window frame having vertical inner andouter grooves or channels 2 and 3 respectively, at each side thereof, inwhich the cords 4 and 5 travel, said cords passing over the pulleys 6 ascustomary and having weights 7 on the other side of the frame.

Speccaton of Letters Patent.

Application filed March 1, 1909.

Patented Jan. 11, 1910. serial No. 480,636.

8 and 9 are drop or slide pieces contained within the grooves orchannels 2 or 3 respectively and at their upper ends secured to thecords 4 and 5 respectively.

10 and 11 are vertical jutting pieces arranged in the window frame tothe outer side of the grooves 2 and 3 respectively and extending beyondthe outer faces of the drop or slide pieces 8 and 9, said verticaljutting piece 10 continuing around the top of the frame and made insections or lengths as usual.

12 and 13 are the sashes, the sash 12 being pivoted at the lower end ofits sides to the drop or slide piece 9, and the sash 13 being pivoted atthe lower end of its sides to the drop or slide piece 8, the pins 14 ofthe oint being encircled by the springs 15, which are arranged to returnsaid sashes to their vertical position after being drawn down and heldtherefrom. It will be seen that the springs 15 return the sashes totheir upper positions against the vertical jutting pieces 10 and 11 andit may here be explained that the particular formation of that channelin the window frame is important in this invention, that is to say, thejutting pieces 10 and 11 form the jambs against which the springs 15hold the sashes. It will also be understood from the description of saidsprings and their arrangement that the strips, to which the sashes arepivoted, are securely held in their lower position during the cleaningof the window for in swinging the sash inwardly, the tension on thesprings brings the said strips into engagement at the upper and lowerends thereof with the walls of the channels, consequently the sashcannot be raised while the sash is in its hori- Zontal position. 16 areweather strips secured to said jambs and here shown as being one meansof further tightening the joint between said sashes and said windowframe in their closed position to prevent the ingress of cold air.

17 is a window fastener of any suitable type and having its partssecured to the top of the lower sash and the bottom rail of the uppersash as customary.

In the use of this window, the fastener 17 is unlocked and the lowersash drawn downwardly and inwardly with the result that it is in aperfectly horizontal position and may be cleaned with ease and whenfinished the upper sash may also be pulled down and folded to ahorizontal position over the lower sash and also cleaned thereby doingaway entirely with the necessity oi' standing to the outside of thewindow. As soon as the glass of the windows is cleaned, the upper sashis raised and swings to its vertical position, completely closing itsdrop piece into the groove and closing to the vertical jutting pieces ofthe traine, thus completely closing in the window opening at the topthereot quite as securely as any window not having the particularadvantages ot' this invention. rlhe lower sash, of course, swings intoplace as soon as the upper sash gets to its vertical position and in theclosed position is locked thereto. The lower sash folds up against itsparticular jutting pieces and against the lower rail oli the upper sash,consequently the whole window opening is securely closed and by adding aweather strip or any other suitable means, it inay be made perfectlytight, in tact inuch inore so than any ordinary window not havingfacilities oiilered by this particular window.

in the vertical positions of the sashes, the operation of the window isprecisely siinilar to any window in regard to lifting up and pullingdown, for the counter-weights 7 balance the weight of the sashes andleave thein in any position that they are placed in.

sashes to the said strips or slide pieces in the said grooves is notdescribed at great length herein, but it will be readily understoodironi the illustrations that the pivot pins 14- niust be securelyfastened in the said drop or slide pieces and in the present form nswinging the sashes to their horizontal podescribed, they are secured bysimple cross pins 1S passing through said pins and the said slidepieces, thus springs encircling the pins laare at one end securelyfastened to the pin and at the other end to the sash, the

said springs being brought to the necessary tension on pulling thewindow inwardly in order to carry it back to its vertical position.

19 are spring catches secured to the lower sash adjacent to the top ofthe said sash,

said catches having the spring-held bolts 2O extending into the grooves2 and respectively in the vertical position of said sashes and retainingsaid sashcs securely in said vertical positions.

ll'vhat l claim as niy invention is:

l. ln a window, the combination with the window traine having verticalchannels therein arranged, said channels having the outer side wallsjuttiug toward the window opening beyond the inner side walls, stripsslidably arranged in said channels and weights drawing on said strips,of window sashes givotally secured at their lower ends to the lower endsotl said strips and springs suitably arranged in relation to the pivotal'tastenings of said sashes and adapted to return said sashes to theirupright position and to retain said strips in their lower position inbringing said sashes to their horizont-al positions.

i2. ln a window, the combination with a window traine having verticallyarranged pieces jutting inwardly toward the window opening, of aplurality of window sashes adapted to fold upwardly against said juttingpieces, a pair of supporting strips slidably arranged in said traineA`pins rigidly g secured adjacent to the lower end of said The arrangementof the pivot point of the strips and extending inwardly into said sashesand helical springs encircling said pins and secured thereto at one endand at the other end to said window sashes and adapted to hold saidsashes against said jutting pieces in the closed position thereof and tohold said strips to their lower position on sitions.

Signed at the city and district of Montreal, in the Province of Quebec,in the Doininion of Canada, this 19th day of February, 1909.
